Pylon signs usually include a box type sign structure either illuminated or non illuminated and can have signage such as neon, LEDs and others incorporated into the structure.
In the past it was normal for this type of sign to use fluorescent bulbs for illumination, but with the new energy efficient LED, many now use LEDs for illumination.
There are a wide variety of plastics used for sign faces along with many different colors and combinations for sign faces and sign letters.
